ABSTRACT: Several airborne and ground-based applications require wide spectral imaging (spanning visible to LWIR) with a single uncooled FPA imager with performance metrics comparable to those provided by image intensifiers or cooled thermal imagers. A single-chip multispectral FPA is desired so that a pilot may electrically switch between the available bands, enhancing target discovery, while maintaining original sight and orientation information. It is also desired that the FPA be lightweight so that the camera can be integrated with pilot"s visor system. Unfortunately, existing technologies (ex. silicon FPA, intensifier tubes, thermal imagers, and InGaAs photodiodes) either have limited spectral response or lack spectral selectivity (thus require filters). Furthermore, the traditional bolometer trade space precludes the development of uncooled high speed and low noise bolometer devices at room temperature. Tanner Research is proposing to leverage recent developments in nanophotonics to circumvent the traditional spectral limitations and bolometer trade spaces. We propose the use of our demonstrated nanobolometer concept, and further develop it into a low noise, high-speed, multispectral, uncooled, silicon-based FPA imager in Phase II. In Phase I, we will provide proof of concept demonstrations in single devices that demonstrate the scalability of our technology across multiple detection bands. BENEFIT: Multi-color uncooled FPA in silicon will enable several surveillance applications from UAV and other lightweight platforms. Low-cost, wide-and-selective spectral response can enable advanced targeting munitions or countermeasures. Lightweight, head-mounted imager system could also benefit special operating forces, first-responders, and search-and-rescue personnel.
